Terracotta Cleaning, Sealing & Maintenance Guide

terracotta cleaning, sealing & maintenance guide PRE-SEALING Terracotta can be extremely porous and will benefit from a pre-sealing treatment. Spirit Pre Seal will act as a compliment to your final seal, giving added water resistance. The bonus of acting as a grout release makes grouting much easier, provides a higher-level grout joint, and a better finish overall.

The tiles can be dip sealed, sprayed, or a lambswool applicator can be used after which the stone can be stacked to dry. Only 1 coat or treatment is necessary, and the Spirit Pre Seal has a 24hr cure time.

IMPORTANT! Do not stack the drying tiles against each other with no air flow, stack them so they can breathe, and remove any excess sealer from the face of the terracotta within 5 minutes.

USING SPIRIT PRE SEAL AS A GROUT RELEASE Prior to grouting you can apply a coat of Spirit Pre Seal to the face of your already laid terracotta. The following day you can grout your stone with ease.

INITIAL CLEANING/GROUT HAZE REMOVAL Once the terracotta has been laid, grouted and washed, a grout residue/haze may be left. It is recommended to wait for 3-4 days for the grout to harden sufficiently before attempting to remove the grout haze in preparation for sealing.

It is advised to keep the floor and or walls protected during this timeframe if work is still being done by other trades, as they may need to work over or near your freshly laid terracotta.

What you will need – (NT Residual Surface Cleaner, NT All Purpose Cleaner, Spirit Doodlebug, bucket, broom, mop) Spirit Safe Acid can also be used to remove the grout haze.

IMPORTANT! - Test first for acid sensitivity before cleaning any surface with NT Residual Surface Cleaner or Spirit Safe Acid. If the stone shows acid sensitivity, use Spirit HDC to remove the grout haze.

1. Sweep and or vacuum the area to remove any loose debris.

2. In a bucket, dilute 10 parts clean water to 1 part NT Residual Surface Cleaner or Spirit Safe Acid and apply to the area that needs cleaning. Use a broom to evenly distribute the solution over the area.

nationaltiles.com.au

3. Allow the solution to sit for 2-3 mins. If you notice that the solution is drying, add more cleaner to keep it wet. *Only clean in sections that you can handle.

4. Now scrub the area with a Spirit Doodlebug (scouring pad.) The multi-directional head attaches easily to a broom handle for easy cleaning in hard-to-reach areas.

5. Remove the solution with a dense mop and rinse the floor with NT All Purpose Cleaner at a dilution of 20 parts clean water to 1 part NT All Purpose Cleaner. If you have access to a wet/dry vacuum it is the ideal way to remove the dirty water.

6. If necessary, rinse the area with clean water and allow it to dry completely before sealing.

SEALING Once the terracotta is clean and dry, final sealing can begin. It is recommended that a breathable penetrating sealer is used. Test first before use, preferably on a spare piece of tile.

• NT Penetrating Sealer can be used for the final seal. Spirit Premium Seal and Spirit NPS are also suitable for use.

What you will need – (Sealer, Spirit Microfibre Applicator, clean white rags, gloves, respirator and solvent suitable tray (for solvent-based sealer only) 2 coats are required, allowing approximately 1 hour in between coats. Follow the directions on the can or bottle very closely.

Please note: Penetrating sealers will not prevent surface etching or scuffing.

MAINTENANCE The terracotta can be cleaned regularly using NT All Purpose Cleaner. If need be, the tiles can be cleaned periodically (every 6-12 months) depending on traffic and wear with Spirit HDC or Spirit Bright As. RE-SEALING Please note: Weather conditions, harsh cleaning methods using high-alkaline, acid or solventbased cleaners will affect the long-term performance of any sealer. Following the appropriate Spirit Guide relating to your substrate will ensure the very best protection. The longevity of your sealer is greatly dependant on the following 4 points: 1. Using a premium quality sealer.

The range at National Tiles are all premium quality, high performance sealers.

2. Proper application of the sealer. This includes the cleaning process prior to sealing.

Sealing a floor that hasn’t properly dried, sealing when it’s too hot or cold, not mopping up excess sealer and not applying enough sealer are a few of the mistakes made.

3. Where the sealed area is? Is it a high traffic area?

Commercial areas that see more traffic and are cleaned daily will need re-sealing before most domestic areas; however, in domestic situations like, outdoor areas, high-traffic internal areas and shower cubicles, these areas will need to be re-sealed more often. If in doubt, contact Spirit Sealers.

nationaltiles.com.au

4. How the floor is maintained?

Cleaning regularly with the wrong types of cleaners will break down the sealer prematurely and may even do damage to your terracotta. The cleaners in this guide have been formulated especially for the stone and tile industry.

This is a general guide for Terracotta, National Tiles always recommends to test first when cleaning or sealing any surface. For more information contact sales@spiritsealers.com
